This invention relates to cushion seat constructions; and it has particular reference to a border frame for a cushion seat comprising a metallic member having a web. portion an external flanges adapted to receive a cover for the seat and means to secure the cover in the space between the flanges, and further comprises a border frame wherein the flanges are reversed on themselves and bent to prolo'videa .socket for the reception of a cross bar for the springs of theseat; all as more fully hereinafter set forth and as claimed.

Cushion seats comprise seatswherein a number of coiled springs are mounted within a border frame and are covered with suitable padding and a fabric. Usually the springs are mounted on cross bars extending between opposite sides of the lower border frame, andthe fabric cover for the entire 2.0 seat is secured adjacent the lower border y frame. `The ypresent invention contemplates the provision of a lower border frame adapted for use in cushion seats.

Various embodiments ofthe principles of the invention are illustrated in the accompanying drawings, wherein F ig. 1 is a fra entary view in perspective of a lower bor er frame and seat elements immediately associated therewith;

The construction shown in Figs. 1 to 4 inclusive comprises a border frame, referred to generally by the reference numeral 2() and a cross-bar 21 provided withk pairs o apertures 22 adapted to receive coiled springs, not shown, which extend upwardly a ainst padding, also not shown. A cover 23 o suitable material, hereinafter simply called the fabric is drawn over the upholstery on the top of the springs, straight down the sides of the cushion and/is secured to the border frame 20 bv means presently to be described.

The border frame 20'consists of a rectangular member of rolled steel, which has an external vertical web 25 defined atits upper 75. portion by an outwardly extending and downwardly turned ange 26, which marks one edge of the metal originallyfused to .form the border frame. The lower portion of the web 25 merges into an'outwardly extending and substantially horizontal flange 27 j which is sharply reversed on itself tov provide a base ortion .28. This` ortion, in turn, is sharp reversed on itsel to form an interior lower dyange 29 which turns upwardly to form an interior'vertical'web 30. which finall vterminates in an inwardly extending), and ownwardly turned flange 31.v It will e observed,

frame is similarv to. the letter I, save that the upper flanges 26 and 31 are turned downwardly and so converge toward the lower flanges .27 and`29.- The space between the outer flanges26 and '-27 lmay be referredvto as the recess 32. A f

The fabric cover 23-which is drawn down around `the sides of the cushion seat is tucked within the recess 32, as best illustrated in Fig. 2. It is here secured by 'means Vof a resilient and rathertaa strip of steel 33 ion Y vvibich is slightly wider than the minimum distance between the flanges 26 and 27, and

which is simply sprung-between these flanges to hold the fabric 23 in place.

The cross-bar 21 is advantageously of inverted U-shape in cross-section and has flattened ends 34 which are bent first upwardly and then downwardly to form hooked portions 35 which are inserted between the Webs 25 and 3C. It will be observed that the bent end of the cross-bar 21 enga es the Bange 31, which, as originally pointed out, is formed b reversing one of the exterior flanges (2%) and subsequently bending the reversed portion to form a socket in which the end of the cross-bar is inserted. ln the instant case, the socket is defined by the space between the webs 25 and 30.

vWhen the cross-bars are positioned. the webs may be clamped tightly together at either side of the ends of the cross-bars as illustrated best in Fig. 4 by the reference numeral 36. Or, the metalmay be punched or the parts welded or other expedient-s resorted to to prevent the cross-bar from slipping. The springs, padding and cover are then positioned, and the fabric 23Ais secured by the resilient strip 33, as indicated above. The spring clip 33 may, of course, be of any length desired, and may be bent to pass around the corners of the frame.

Another form of border frame is shown in Figs. 5, 6 and 7. In this case, the upper inner flange 31 is omitted, and the inner extremity of the metal originally forming the border frame terminates with the upper edge of the inner web 30a. rlhe cross-bar 21 is formed with' an end portion provided with a very sharp bend 38. The remaining details of the construction and method of assembly are believed to be obvious in view of what has been said with respect to the construction shown in Figs. 1 to 4 inclusive. These views also show a bottom fabric 23a, which may be included in air bound seats, and secured in the recess 32 with the fabric 23. v

The modification shown in Figs. 8, 9 and 10 consists of a single vertical web 40 having upper and lower outwardly extending and converging flanges 41 and 42, both of which are sharply reversed on themselves,

as indicated at 43 and44. The cross-bar 21 has a llattened end portion 45, which is bent downwardly and then outwardly as indicated by the flange portions'46 and 47. In

vassembly, the flange 47 is thrust in the space between the flanges 42 and 44 of the border frame. The flange 47 is of such length as to permit of close contact of the flange 46 with the inner face of the web 40. Thereafter the cross-bar 21 issecured to the border frame b clamping, welding, or like expedient. he fabric 23 is secured between the outer converging flanges 41 and 42 in the manner previously described.

The modification shown in Figs. 11, 12 and 4 13 comprises a lower border frame having a lower outwardly extending flange 50, exterior vertical webs 51, and an upper outwardly extending flange 52 converging toward the flange 50 to provide a recess for positioning a resilient clamping strip 33, all in a man ner similar to that previously described. The upper flange 52 is sharply reversed on itself as indicated at 53 and is then bent downwardly to form an interior vertical web 54 merging into an inwardly projecting lower flange 55. The cross-bar 21 is provided with a horizontal Hat portion 57 which is turned upwardly to provide a flange 58 adapted to be seated in the socket formed by the webs 51 and 54, and to be aligned by the inwardly projecting flange 55. The method of assembly is the same as that previously described.

From the foregoing description, it will be seen that the invention provides a lower border frame in which there are a pair of nutwardly extending flanges adapted to receive the seat fabric, and further, that one of the flanges is reversed and bent to form a socketl 1. A cushion seat comprising a lower bor- 1 der frame having a vertical web and exterior upper and lower flanges, one of said anges inclined towards the other, thereby forming a recess to receive a seat cover, a clamping strip adapted to be inserted between the flanges to secure the cover to the frame, the other flange being reversed and bent to form a socket for the end of a cross-bar and a crossba-r having an end in said socket.
